Sara Elizabeth Pendergraft

I am trying to help my nine-yr.old granddaughter to find her Pendergraft Family roots. Her father was James Brent Pendergraft. Her grandmother was Brenda Pendergraft. Would like to find out the rest of the family for her. This family was in the Palo Pinto Co.,and Parker Co.,Texas area a few years ago. Any help will be appreciated. Thank You.
